If there is one weakness that the iPhone has right now, it has to be the ability to allow other processes to run in the background. Understandably, the iPhone is not expected to perform in the same way that PCs and notebooks can, allowing other processes to run while the main app is on the foreground. However, Apple seems to be seriously considering this option to push through.

One would think that if this were to happen, a lot of things may have to be considered. One is the ability of the iPhone to handle such processes and perhaps upgrading or replacing some chips or parts to provide more support to the default apps.

Earlier today, Dan Frommer of Silicon Alley Insider cited sources in the mobile industry saying that Apple was serious about allowing background applications. John Gruber of Daring Fireball backed this up , saying he heard something similar from a decent source a few months ago. I’ve just spoken with a trusted source who confirmed the news as well.
